VENDING MACHINE Applicatonl'ed January 19, 1925. Serial No. 3,431.

The. object of my device isto. make a vend'- ing machine to e used'particularly lfor liquids such as liquid's'oap. A furtherobject is to;devise. a vending machine made operative; by the insertion ot' a coin,such as a'penny; one that will be inoperative unless a coin or slug oli'exact previously determined" dimension. is inserted. A still furtherobject is tov make a machine of the type described, of lfew and. simpleparts that lend themselves readily to multiple product-ion and that maybe easily assembled;

With' these. andfother objects in View, my inventionI has relation to.cert-ain novel: featuresfof construction: and arrangement of parts; aswill be hereinaftermore yfully described",` pointed-out in the. claims,and illustrated' the drawing,` ini which,

Numeral 8i designates the casing for my device which is secured totheWall hoard 9 in any conventional manner.

The casing 8 provides an upper space 10 for the reception of' the liquidcontainer 11, and a lower Space 12 for a coin receptacle 12- and myvalve mechanism 14, together with its delivery spout. The liquidcontainer 11v is supportedin the casing 8 on'the side wall; brackets'113, the valve mechanism 14 being secured to the bottom ofthe liquidcontainer 11' and hanginginthe lowerspace Numeral 14:a designates adelivery spout in lui-d-Y communication with the valve mechanismk 1&4 atone end, and passing into the delivery hole 15 inthe casing 8 at theother end. In the front wall of the casingvS, im-

f mediately in front of the valve mechanism lglfuiid communication valvemechanism 111i, is turned. The coin 16, after having performed itsfunction, drops into the lower space 12, or coin receptaclev 12a. Thevalve mechanism 11 is so constructedy that the valve well 17 is normallylled with liquid and in cation with the liquid; container 11 by means ofa conduit 18.

The construction of the valve mechanism is the following- :--1t issecuredA to, the hottom of the liquidcontainer 11 by means ot' screws19'passingthrough the journal plate 20, and hy means of the deliveryspout 14a andv theconduit 1S. 'glie conduit 18 is preferably soldered tothe bottom olf thev liquid container 11./ The cylindrical housing 21 is:fformed integrally with the delivery spout 14av and the. conduit spout18, establishing between them there thitougfh.V A; frustofconigcal hole222 passes through the cylindrical housing' 21 from face to face. wallsoi'l which form they valve well 17, is positioned in the hole 22.Y Ahole 21 is formed' the shell 23;, establishing iluid communicationbetween the valve well 17 andthe-exterior of the shell. Numeral 25desigr'iates a; relatively smaller air hole likewise establishing aircommunication between the valve well 17 and` theV exterior of the shell.hole establishing aircommunication het\'veen the exterior of the shell23 and the hole 22.. When theshell 23 is in the position shown inf Fig.3 in solidY lines, the liquidmay flow 'from they liquidy container 11into the well 17 through the conduit 18 andV the hole 24. Then the shell28: is rotated a portion of a turn to the left until the holeQt is inregistration with the mouth of the spout 11 and ilu id communirlhetruste-conical shell 23, thek Numeral- 262 designates a small air thecontents of the-.well 17 will he permitted toflow gravitationallythi-'ough the spout 14a.

The inid communication between the liquid container 11 and: the 'valvewell 17 is broken during this time. By these means the contentsgof thewell 17 maybe delivered to the spout 14 by a turn of the shell 23.

A disk 27 having lugs 28 and 29 formed on its periphery isV castintegrally with a shaft-7 30 oit lesser diameter, which shaft is formedintegrally, centrally, on the shell 23. @n the shaft 30 pin 31 is formedto which at one end is secured the coileoln spring 3Q.b the other end ofwhich is secured to the hottom (di the liquid; container by they screw33. rfhe coiled spring 32 maintains the shell 23 normally in theposition shown by solid lines in Fig. 3, that is, in the position forfilling the well 17.

Numeral designates ashaft to which `is keyed the disk 35; formedintegrally with the disk 35 are formed the shoulder 36 and the shoulder37 of lesser diameter than the shoulder 36, and the left end of theshaft 34 (Fig. is recessed longitudinally and asmall coiled spring issecured therein and extends outwardly a short distance beyond the end ofthe shaft. A drift pin 38 passes through holes in the shaft 1Gb and thehole 39 in the shaft 34, thereby connecting selectively the shaft 34with the shaft 1G. The shaft 1.61 passes through a hole in the side wallof the casing 3. The shoulder 37 is jonrnaled in a hole in the journal.plate 20. It will be seen that when the handle i6 is turned that thedisk 35 will be rotated. The purpose of the structure thus far describedandy to be further described hereafter is to enable the shell 23 to berotated when the handle loft is turned, but only when a coin is inserted(by means to be subsequently described). The handle may be turned,together with the disk 35 without the insertion of a coin, but in thatevent there will be no engagement between the disk 35 and the disk 27.The engagement of these two disks is necessary in order to rotate theshell 23, and this engagement is only brought about by the insertion ofa coin and the turning of the handle 16. The coin acts as a means foractuating a clutch or dog (to be subsequently described).

In order to hold the disk 35 in its normal position, a coiled spring 49is positioned over the shoulder 3G, between the disk 35 and the journalplate 20, the one end being secured to the shoulder 36 and the other tothe journal plate 20. The disk 35 has a peripheral flange 4l formedintegrally therewith, in which flange is formed the arcuated coinreceiving recess 42 and the chordal slot 43. In the space between theperipheral flange 4l and the cent-ral shaft are formed the followingelements, the upper surfaces of all of which are in the same plane withthe plane of the flange 41. A bent lever 44 fulcrumed at 45 has a knob46 formed thereon, which extends through a slot in the arcuated coinrecess 42. At the end of the lever 44 a dog 47 is rotatively secured,its other end extending into the chordal slot 43. It

will be seen that when the knob 46 is moved inwardly that the dog 47will be moved to the left and its end made to protrude beyond thechordal slot 43. In order to normally hold the dog 47 in such a positionthat it will not protrude beyond the periphery of the disk 35, a knob 49is formed on its lower surface, and a leaf spring 50 secured to the disk35 at one end contacts the knob 49 at its other. Vv'hen a coin 1G isinserted in the coin receiving recess 42, the dog 47 will be made toarotrude beyond the periphery of the disk 35.

In the center of the disk 27 is formed a recess 5l into which fits thespring at the end of the shaft 34. In assembling, the disk 27 and thedisk 35 come in sliding contact with each other. In order to secure thelengagement of these two disks, the dog 47 may be pressed to its extendedposition so that its end meets the lug 28. Then the disk 35 will carrythe disk 27 with it. VThe coin initially causes the dog 47 to engage thelug 23, and the .frictional engagement be tween the dog 47 and the lugcontinues the contac. as long as the handle 1Ga is turned, and this issuflicient to cause the flow of the liquid out of the spout. The handlemovement isA limited to a small part of a full turn. IVhen the handle isreleased, it assumes its normal position by rotating in the oppositedirection, the dog 47 resumes its normal posit-ion, the engagementbetween the disk 27 and the disk 35'is broken, and the shell 23 resumesits normal position.

In order to limit the rotational movement of the shell 23, a metal strip5l?L is secured by means of the screws 52 on the end of the shell 23.This strip extends beyond the periphery of the shell and engages lugs 53and 54 on the housing 21.

The progress of the coin through the device is the following. It entersthe coin slot 15"L and passes into the coin receiving recess 42. Thenthe handle 16 is turned, the coin is pressed against the top of therecess rand against a project-ion 53 and then downwardly against theknob 46, thereby causing the lever 44 to function, as previouslydescribed. The coin continues and falls into the lower space l2. It willbe seen that by exact designing and the shaping of the coin receivingrecess 42 that only a coin having the exact dimensions of the genuinecoin will actuate the device.

The spring 32 serves to return the valve 23v and disk 27 to startingposition after a manipulation to deliver the contents of the well 17,and the metal strip l5n and stop 53 limit the movement of the valve sothat the opening 24 normally registers with the conduit 1S. The spring40 serves to return the disk to starting position and the stop 55,carried by disk 35 and lug 29 on the disk 27 limits the movement of thedisk 35 so that the coin recess 42 normally registers with the coin slotl5.

Obviously so long as the dog 47 resides wholly within the disk 35,manipulation of the handle 16a will have no effect upon the valve 23.

Assuming the parts are in their normal positions, as just described; thewell 17 lled and a coin inserted as shown by solid lines in Fig. 5 andby dotted lines in Fig. 6, and

the handle 16a and disk 35 turned clockwise,

it Will be noted that the coin will be engaged by the projection 53 andforced to the left (in Fig. 6) and thus move the lever 44 and 'dog 47 tothe left a distance,y t0 cause the dog to project beyond the peripheryof the disk 35 where it will engage the lug 28 and hence carry the disk27 and valve along With it, so that the opening 24 inthe valve Will bebrought to register with the delivery spout 14a. A release of the handlepermits the springs 32 and 40, stop 55 and lug 29, and metal strip 51and stop 53 to function as recited.

IVhat I claim and mean to secure by Letters Patent is:

In a device of the character described, a valve mechanism, a disk havinglugs formed thereon, secured to said valve mechanism, a

second disk secured to a shaft, the end of which is rotntively securedin a recess formed in the center of said first disk, means for rotatingsaid shaft, said second disk havingr a coin slot formed therein, a leverrotatively secured at one end positioned therein, a dog rotativelysecured at one end tothe free end of said lever, said dog being` tionedin a- Slot in said disk, the slot, lever, and dog being so positionedrelative te each other that when a coin is inserted in the coin slot of'said disk and said shaft is turned, said levcr will be oscillated andsaid dog moved laterally to protrude beyond the 1 periphery ot' saidsecond disk and engage ene of the lugs 0n said first disk, therebyturning said first disk and said valve mechanism.

In testimony whereof I aliiX my signature.
